To all whom it may concern:

Be it known that I, RUDOLPH J. DAASE, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Gas-Burner Attachments for Hot-Air or Hot-Water urnaces; and I do hereby declare that the following is a full, clear, and exact descrip tion thereo This invention relates to gas heaters especially adapted to be installedfurnace of either the hot air or hot water type, thereby affording a clean, safe and efiicieiit substitute for coal, wood or oil as a The principal object of my invention is to provide a simple, safe and economical as burner that can be easily attached to a re chamber of a hot air or hot water furnace without disturbing its operation with coal or other fuel when desired.

Another object of my invention is to provide a gas burner attachment for a hot air or hot water furnace which is adapted to be regulated by any form of automatic control.

The invention in one practical form in which it may be embodied is illustrated in the accompanying drawing, in which:

Figure l is an elevational view partly in diagram showing my invention attached in the fire chamber of a hot air furnace.

Fig. 2 is a sectional view through the furnace taken on the line 2-2 of Fig. 1, and

Fig. 3 is a detail sectional view showing the regulating valve.

In the drawings 1 is the ordinary type of hot air furnace having mounted within its fire chamber 2 a coil 3 which is made in two parts in order that the coil might be inserted into the fire chamber through the ordinary coal door. The coil is then assembled by the unions 4 and held in proper place by brackets 5 carried on the side of the fire chamber.

Mounted at intervals around the coil 3 are gas burners 6 of the ordinary air mixing type and attached to the coil and extending through the walls of the burners is a supply pipe 7 which is provided with a control in a heating valve 8 of the ordinary rotary type. The rotary shut-ofli plug 9 contained within the Valve casing is provided at one of its outer ends with an arm 10 carrying a counterbalanced adjustable weight 11. The arm 10 has a movement between pins secured to the plate 12 carried on the casing of the valve. This movement of the arm 10 will permit varying amounts of gas to be supplied to the burners.

It will be noted, as shown in Fig. 3, that when the arm 10 rests upon the pm at the limit of its closing movement, the passage in the plug 9 is still slightly in register with the ports in the valve thereby admitting a small supply of gas. The purpose of this is to maintain a small flame in the burners at all times in order to prevent any leakage of gas fumes which might occur should the flame be extinguished entirely.

The arm 11 has attached to its outer end a suitable chain or cable 13 which is passed over the necessary pulleys to an electrically operated control 14 which in turn is governed by a thermostatic regulator 15 that can be placed in any convenient location. It will be seen that the valve 8 is normally held in its closed position by the counterbalanced weight 11 when upon the operation of the electrical control the cable 13 will be drawn upwardly thereby opening the valve.

The supply pipe 7 carries a branch pipe 16 which extends through the walls of the furnace and is provided at its end adjacent the gas burners with a pilot light 16, the purpose of which is to initially ignite the burners. Both the supply pipe 7 and the branch pipe 16 are provided with shut-off valves 17 and 18 to positively shut off the supply of gas when the burners are not in use. 7

From the foregoing description it will be seen that I have constructed a gas burner which is safe and simple in operation and which can also be readily attached to any standard form of furnace without altering the same. Furthermore, it will be noted that I have shown my invention placed within the fire chamber above the line of the coal door, where it will in no way interfere with connecting the pipe sections, and a single the operation of the furnace should it be desupply pipe and burners carried by the coil. 10 sired to use coal or other fuel. 1 In testimony that I claim the foregoing I That I claim is have hereunto set my hand at Milwaukee,
